HINGE.

Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed January 26, 1917. Serial No. 144,641.

To all whom it may concern Be it known that I, AnoLrH C. LUTTER, a citizen of the United States, residing at Glenview, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hinges specially adapted for use on screen doors which are taken down periodically, and also for use in other places where the hinges are preferably formed of readily separable parts; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of a hinge constructed according to this invention. Fig. 2 is a plan view of the same. Fig. 8 is a detail front view of themain portion of the hinge. Fig. 4 is a detail front view of the plate which receives the locking wedge. Fig. 5 is a plan view of the same. Fig. 6 is a detail view of the locking wedge.

The main portion of the hinge is formed of a plate 2 and a frame 3. These two parts are provided with overlapping flanges or knuckles 4 and 5 at their upper and lower edges, and a pivot pin 6 passes through these knuckles so that the two parts 2 and 3 are pivoted or, hinged together. The plate 2 has holes 7 for screws, and is permanently secured to the door frame. The two parts 2 and 3 may be provided with any approved form of spring or springs such as commonly used on screen doors for holding the door closed. g;

The frame 3 has horizontal arms 8 at its top and bottom, the bottom arm being shorter than the top arm, and each arm has a hook-shaped socket or guide 9 at its free 15. The plate 12 is arranged in the space between the two arms of the frame, and so that its guides come in line with the aforesaid guides or sockets on the frame.

A locking wedge 18 is provided, and is driven into the aforesaid guides or sockets, as shown in Fig. 1, so that it locks the plate 12 securely to the frame 3. 'This wedge is easily removed and replaced, so that the screen door can be taken down and put up as often. as desirable without removing any screws or nails. Each screen door has two similar hinges secured at its upper and lower parts, and these hinges are constructed so as to be inexpensive, and they are not liable to get out of order.

What I claim is:

A hinge fastening, comprising a pivoted frame having at its top and bottom two arms of unequal length provided with hookshaped guides at their free ends, said frame having also a pair of guide lugs struck up from its body'portion and arranged adjacent to and between the other end portions of its said arms, a fastening plate provided at its edges with guides of unequal length the ends of which correspond with and fit between the said guides and guide lugs of the frame, and a connecting wedge which engages with the guides and guide lugs of the fastening plate and frame.

In testimony whereof I have affixed my signature.

- ADOLPH C. LUTTER.
